MAGNITUDE 4.2

Noticeable shaking of indoor objects. Damage is unlikely.

The scale is logarithmic: this released about 63 times the energy of a magnitude 3.0, roughly the energy of 30 tonnes of TNT.

5 KM DEEP

Shallow earthquakes release their energy close to the surface, so they are felt more strongly, and do more damage, than deeper earthquakes of the same magnitude.
